About this 0.51ct natural cushion diamond

This 0.51ct natural cushion sits in the half to three-quarter carat band, graded I colour (near-colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 2547430629. Listed at 9 retailers as of November 4, 2026, with prices from $965 to $2,612, a $1,647 spread on the same certified stone. Flawless Fine Jewelry lists it at $2,612. Flawless clarity in sub-one-carat stones is rarely visible to the naked eye over VS1, so you are paying a meaningful premium for grade rather than appearance.
